A  LIST  OF  THE  GENERIC  AND   FAMILY  NAMES  OF 
RODENTS. 

BY  T.  S.  PALMER. 


Generic  names  of  mammals  have  undergone  many  changes  in 
recent  years,  and  in  no  group  is  this  more  apparent  than  in  the 
Rodentia.  Not  only  have  new  names  been  proposed  for  a  host 
of  new  forms,  but  many  well-known  genera  now  appear  under 
names  long  forgotten,  but  revived  in  obedience  to  the  law  of 
priority.  Linnseus,  in  1758,  recognized  only  six  genera  of  ro- 
dents (including  Rhinoceros!) ;  Agassiz,  in  1842-'46,  recorded  about 
220  generic  names  in  this  order,  and  Marschall,  in  1873,  added 
65  more,  making  a  total  of  somewhat  less  than  300.  The  present 
list  contains  more  than  600  (a  large  pro})ortion  of  which  are,  of 
course,  synonyms),  comprising  perhaps  15  percent  of  the  entire 
number  of  generic  and  subgeneric  names  ever  proposed  for 
mammals. 

Recent  changes  in  the  nomenclature  of  the  Rodentia  are  well 
exemplified  in  two  important  papers  which  have  appeared  dur- 
ing the  past  few  months— one,  by  Mr.  Oldfield  Thomas,  entitled 
'On  the  Genera  of  Rodents';^  the  other,  by  Dr.  E.  L.  Troues- 
sart,  comprising  part  of  the  second  edition  of  his  '  Catalogus 
Mammalium.'  The  former  paper  gives  merel}^  a  list  of  the  groups 
of  living  rodents  which  the  author  considers  worthy  of  generic 
rank,  together  with  references  to  the  original  description  of  each 
genus.     Trouessart's  Catalogue,  more  ambitious  in  its  scope,  is

intended  to  include  all  the  species,  living  and  extinct,  now  recog- 
nized. Even  with  these  aids  the  student  will  often  find  difficulty 
in  looking  up  synonymy  or  determining  the  earliest  name  of  a 
genus,  for  Thomas  gives  only  about  one-third  of  tlie  names,  while 
Trouessart  does  not  pretend  to  include  all  the  generic  synonyms 
and  frequently  omits  references. 

The  present  paper  differs  from  either  of  those  just  mentioned. 
It  is  neither  an  index  nor  a  catalogue  of  recognized  genera,  but 
merely  an  attempt  to  bring  together  all  the  names,  generic  and 
subgeneric,  ever  proposed.  It  is  not  complete  in  itself,  inasmuch 
as  it  gives  neither  references  to  descriptions  nor  localities ;  but 
the  authority,  date  of  publication,  and  type  or  included  species 
under  each  name  will  throw  some  light  on  these  points.  In  ar- 
ranging this  list  everything  has  been  subordinated  to  convenience 
of  reference.  Genera  and  subgenera  have  been  treated  alike  and 
distributed  under  families,  while  the  alphabetical  arrangement  has 
been  followed  both  in  the  sequence  of  higher  groups  and  in  the 
names  under  e^ch  family.  Some  difficulty  has  been  experienced 
in  properly  grouping  the  genera,  and  about  a  dozen  names  have 
not  been  referred  to  any  family  for  lack  of  sufficient  information 
regarding  their  status.  Thomas'  classification  of  recent  genera 
has  been  followed,  except  in  the  case  of  Lophiomyidas,  which  is 
given  full  family  rank,  instead  of  being  placed  as  a  subfamily 
under  Muridse.  To  these  22  groups  have  been  added  5  additional 
families  of  extinct  rodents  recognized  by  Zittel,'  making  a  total 
of  27  families.  More  than  200  names  occur  under  Muridse,  and 
for  simplicity  they  have  been  placed  under  subfamilies,  but  this 
is  the  only  instance  in  which  the  alphabetical  arrangement  of 
the  family  has  not  been  followed.''' 

The  date  is  alwa3^s  the  year  of  actual  publication,  often  very 
diff'erent  from  the  date  of  apparent  publication.  For  example, 
the  description  of  Schizodon  was  published  in  the  Proceedings  of 
the  Zoological  Society  of  London  for  1841,  but  it  did  not  actually 
appear  until  March,  1842.  Arctomys  was  described  in  a  part  of 
the  fourth  volume  of  Schreber's  Saugthiere,  issued  in  1782,  but 
the  name  was  first  published  on  plates  accompanying  this  work, 
which  are  known  to  have  been  distributed  in  1780.     Schizodon

"^  I  am  indebted  to  Mr.  Thomas  for  looking  over  the  genera  of  Miiridx 
and  Octodontidse  and  for  several  suggestions  as  to  the  arrangement  of  the 
list.

is  therefore  quoted  as  1842  and  Ardomys  as  1780.^  Preoccupied 
names  have  been  marked,  and  cross-references  made  to  those 
proposed  to  replace  them.  A  few  names  have  become  ahnost 
unrecognizable  by  reason  of  the  changes  they  have  undergone 
in  the  process  of  emendation.  Among  such  may  be  mentioned 
the  correction  of  Aplodontia  to  Haploodus,  Pithecheir  to  Fithe- 
cochirus,  and  Coelogenus  to  Genyscoelus.^  The  original  spelling  is 
always  given,  but  no  attempt  has  been  made  to  include  all 
variations,  although  the  more  important  have  been  noted.  If 
the  first  letter  of  a  word  has  been  changed,  both  forms  have 
been  inserted  in  the  list,  but  other  changes  have  been  indicated 
in  foot-notes. 

Each  genus  is  followed  by  the  type  or  species  on  which  it  was 
based.  When  no  type  was  designated  and  none  has  been  indi- 
cated by  a  subsequent  reviser,  all  the  species  are  mentioned  in 
the  order  given  in  the  original  description.  No  doubt  some 
errors  will  be  detected  here,  for  at  first  an  attempt  was  made  to 
determine  the  types  for  as  many  genera  as  possible.  This  plan 
was  subsequently  abandoned  in  favor  of  an  enumeration  of  all 
the  species  originally  mentioned,  but  some  cases  of  elimination 
may  have  escaped  correction. 

More  or  fess  lack  of  uniformity  exists  in  the  nomenclature  of 
certain  families,  as,  for  example,  in  the  cases  of  the  American 
Porcupines  and  Chinchillas.  Thomas,  considering  the  New 
World  Porcupines  worthy  of  separation,  erected  the  family  Ere- 
thizontidse,  and  Trouessart,  a  few  months  later,  recognized  the 
same  group,  bat  renamed  it  Coendidas.  No  less  than  three  family 
designations  for  the  Chinchillas  are  in  common  use — Chinchil- 
lidWj  Eriomyidse,  and  Lag  ostomy  idse.  Such  a  condition  of  things 
is  obviously  unnecessary,  and  can  only  lead  to  confusion.     As 

*  While  this  paper  was  in  press,  my  attention  was  called  to  Sherborn's 
announcement  of  the  discovery  of  Lacepede's  well-known  *  Tableau 
Methodique'  (usually  quoted  1801),  in  the  Didot  edition  of  Buffon's 
Histoire  Naturelle,  Quad.,  vol.  XIV,  1799  (Nat.  Sci.,  XI,  p.  432,  Dec, 
1897).  Lacepede's  genera  Agouti,  Arvicota,  Coendou,  Hamster,  Pika,  and 
Talpoides  therefore  date  from  1799,  instead  of  1801,  but  the  necessary 
corrections  could  only  be  inserted  in  the  cases  of  Pika  and  Talpoides. 

'^In  explanation  of  this  remarkable  emendation  the  author  says:  "  Le 
u  grec  ne  repondant  pas  a  I'u  latin,  le  nom  de  Cuvier  \_Coelogenus']  n'est 
pas  acceptable,  puisqu,  il  renferme  une  faute  d'orthographie ;  et,  pour 
faire  un  nom  d'apparence  reellement  latine,  il  aurait  au  moins  fallu 
^crire  Genyscodus  et  non  Coelogenus.^'    Liais,  Climats  du  Bresil,  1872,  p.  537,

an  aid  in  selecting  the  proper  name  in  such  cases  and  to  help  in 
determining  questions  of  priority,  it  has  seemed  best  to  give 
under  eacti  group  all  the  family  and  subfamily  names  based 
on  genera  belonging  to  it.  Full  references  have  also  been  in- 
serted, inasmuch  as  authors  seldom  indicate  the  place  where 
such  names  were  first  published.  Groups  first  described  as  full 
families  and  afterwards  reduced  to  subfamilies  have  merely  a 
reference  to  the  original  description,  but  those  first  introduced 
as  subfamilies  and  afterwards  raised  to  family  rank  have  refer- 
ences to  both  places  of  publication.  This  part  of  the  list  has 
been  limited  strictly  to  names  ending  iit '  idx '  or  '  inse^''  the  only 
exception  being  old  designations  with  the  closely  related  termina- 
tion '  ma.'  Here,  as  elsewhere,  the  object  has  been  merely  to  bring 
together  under  each  family  all  the  available  names,  without  at- 
tempting to  discriminate  between  synonyms  and  names  which 
have  a  claim  to  recognition.' 

This  list  is  supplementary  to  a  complete  alphabetical  index  of 
the  genera  of  mammals,  containing  full  references  to  descriptions 
and  localities,  which  is  now  almost  ready  for  the  press.  The  data 
relating  to  the  Rodentia  are  here  grouped  under  families  and 
published  in  condensed  form  for  the  purpose  of  inviting  sug- 
gestions and  criticisms  as  to  arrangement,  type  species,  and 
grouping  of  genera.  The  list  is  therefore  merely  an  experiment. 
Although  the  names  have  been  brought  together,  much  remains 
to  be  done  in  working  out  the  synonymy  of  types,  but  such  work 
properly  belongs  to  the  specialist  and  the  reviser  of  groups. 
When  this  has  been  done  some  examples  of  duplication  of  names 
will  probably  be  found  even  more  striking  than  the  case  of  the 
lemmings,  in  which  a  single  species  {Mils  torquatus  Pallas)  has 
served  as  the  basis  for  five  or  six  nominal  genera. 

As  a  help  in  distinguishing  the  names,  extinct  genera  are 
printed  in  italics ;  an  asterisk  (*)  indicates  that  the  original 
description  has  not  been  seen;  a  dagger  (f)  that  the  name  is 
preoccupied,  and  a  double  dagger  (J)  prefixed  to  a  family  or 
subfamily  that  the  name  is  not  available,  either  because  the 
genus  on  which  it  was  based  is  preoccupied  or  because  it  is 
antedated  by  some  other  valid  name. 

^  Forsyth  Major  has  recently  proposed  Nesomywfe  for  certain  Old  "World 
mice  usually  classed  under  Cricetinx ;  but  as  he  does  not  give  the  limits 
of  this  group  Thomas'  classification  is  necessarily  followed,  although 
Nesomyinx  may  be  entitled  to  subfamily  rank  as  much  ?is  the  group  under 
which  it  is  placed,
